構造。 A plurality of cylinders arranged in an engine body, a water jacket forming a passage continuously extending around the group of cylinders to the exhaust side and the intake side of the cylinders, and the water jacket,
a supply port located on the exhaust side of the cylinder and provided in the wall of the engine body for supplying cooling water to the passage of the water jacket; and a supply port of the water jacket located on the intake side of the cylinder. a cooling water outlet formed in the engine body and communicating with the engine body, and a water jacket that narrows the passage of the water jacket so that the flow rate of the cooling water supplied from the supply port is located on the intake side of the cylinder. 1. An engine structure characterized by comprising a flow passage restrictor that restricts flow to a passage side portion of the water jacket located on the exhaust side of the cylinder so that more water flows to the passage side portion of the water jacket than to the passage side portion of the water jacket.
